A player spelled out the male reproduction organ with CV waypoints a few days ago. I have also seen folks draw said organ with CV waypoints.
I remember lots of different patterns created with CV's. Used to crack me up but rarely see it anymore.
For the rest, I saw the accused on bish in control of 217 but it was in a far and pointless corner. The most he could have done is prevent others from using it for defense. The rest of his squad was on another country for sure, but I don't believe it was the country even close to the cv area.
The only real answer for this dickishness and for good gameplay in general, is the cv can only be held by a person on or in range of (purple) said cv. But that is a wishlist item.
For the ban, possibly you using chat report was the cause for whatever ban was received. Possibly they reviewed chat and found nothing at all and felt it was malicious and instead banned you. That is of course taking fully and only into account your insistence of no other possible reason beyond .report chat.
Good luck either way, don't let a game get you worked up, everyone plays their own way whether it seems to be acceptable to others or not. And like your reference to freedom of speech, this is how it should be, to a point as someone else pointed out. What is that point? That is they grey area that makes the BBS so much fun.
